Child performers from Broadway shows School of Rock, Finding Neverland, Matilda the Musical and others will gather Sept. 2 and 3 at 54 Below cabaret to perform and record the score to the 1967 musical You're a Good Man, Charlie Brown for Broadway Records.

Tickets are now on sale for the event, titled "Happiness is... 54 Below Sings You’re a Good Man, Charlie Brown!" The kids will sing the 1999 Broadway revival version of the score, which combines the original Grammy-nominated music by Clark Gesner, with additional music from Andrew Lippa.

The musical is based on Charles Schultz' comic strip "Peanuts," with songs for Charlie Brown, Lucy, Linus, Snoopy, Schroeder and the other precocious kid characters of the strip.
